Field repairs are limited to replacing line cords (with approved types), replacing belt clips, and
replacing batteries. Attempting any repair beyond this at field level is liable to damage the
instrument and will invalidate the manufacturers warranty. Check your company policy before
considering any repair. Although limited field repair may be possible your company may have a
policy of centralised repair.
Remove the three hatch cover screws. Replace the cord by loosening the
terminal screws. Connect a new, standard cord as per the diagram. Tighten the screws firmly
but do not use excessive force. Make sure the battery cover sits down properly before securing
it with the 3 screws.
Wrap the line cord loosely around the handle or preferably make a few loops and pass them
through the belt clip.
Tele300B is highly impact resistant. Even if dropped from a great height onto concrete
Tele300B should survive without permanent damage. In the event that the gasket seal should
bulge out on impact it is usually possible to gently ease it back into position with a blunt tool. Do
not attempt to open the case to make a repair nor should any force be used or the gasket may
split. If a simple local fix is not possible it should be returned for repair.
Please note that the waterproof seal integrity can be damaged by a high impact. If in doubt,
please have your unit checked. Use of the unit while the seals are damaged may invalidate the
warranty.
